Physical Activity of ?7.5 MET-h/Week Is Significantly Associated with a Decreased Risk of Cervical Neoplasia.

ABSTRACT: Cervical cancer is one of the most prevalent malignant neoplasms worldwide. We investigated whether leisure-time physical activity is sufficient to decrease the cervical neoplasia risk and provide suggested guidance of metabolic equivalents of task-hours per week (MET-h/week) spent on leisure-time physical activity to prevent cervical neoplasia. Ultimately, 433 participants, including 126 participants with cervical intraepithelial neoplasia I or higher disease (?CIN 1) and 307 healthy controls, were recruited. All participants completed a standardized questionnaire about leisure-time physical activity engagement (MET-h/week) and a general health questionnaire and had cervical specimens taken to detect human papillomavirus (HPV) infection. CIN 1 staging was identified from the specimens. Participants with physical activity of ?3.75 MET-h/week had a significantly lower CIN risk compared to those with physical activity of <3.75 MET-h/week (p = 0.01). However, among participants with HPV infection or smokers, the minimal requirement of leisure-time physical actively to lessen the CIN risk was ?7.5 MET-h/week. Lifetime leisure-time physical activity of ?0.12 MET-h/week-year also significantly decreased the CIN risk, but women with HPV infection needed ?13.2 MET-h/week-year to protect them from a CIN risk. We concluded that regular leisure-time physical activity of ?7.5 MET-h/week and sustained lifetime leisure-time physical activity ?13.2 MET-h/week-year are vital factors for protecting women against cervical neoplasia risk.

Project description:OBJECTIVE: We investigated whether obesity, physical activity, and calorie intake are associated with the risks of cervical intraepithelial neoplasia (CIN) and cervical cancer. METHODS: We enrolled 1125 women (age, 18-65 years) into a human papillomavirus cohort study established from 2006 to 2012. Multinomial logistic regression models were used to estimate crude and multivariate odds ratios (ORs) and the corresponding 95% confidence intervals (95% CIs), and to assess whether body mass index (BMI), height, weight, total calorie intake, and physical activity were associated with the risks of CIN and cervical cancer. RESULTS: Cervical cancer risk was positively associated with BMI and inversely associated with physical activity. When compared with women with a normal BMI (18.5-23 kg/m(2)), the multivariate ORs (95% CIs) for those overweight (23-25 kg/m(2)) and mild obesity (≥25 kg/m(2)) were 1.25 (0.79-2.00) and 1.70 (1.10-2.63), respectively. When compared with women with the lowest tertile of physical activity (<38.5 MET-hours/week), the ORs (95% CIs) for cervical cancer were 0.95 (0.61-1.48) and 0.61 (0.38-0.98) for women with medium physical activity (38.5-71.9 MET-hours/week) and those with high physical activity (72 MET-hours/week), respectively (p for linear trend = 0.03). The CIN2/3 risk was inversely associated with physical activity after adjustment for confounders. Compared with women with low physical activity (< 38.5 MET-hours/week), the ORs (95% CIs) for CIN2/3 were 0.64 (0.40-1.01) and 0.58 (0.36-0.93) for the medium and high physical activity groups, respectively (p for linear trend = 0.02). Total calorie intake was not statistically associated with the risks of CIN and cervical cancer after adjustment for confounders. CONCLUSION: Our results indicate that in addition to screening for and treatment of CIN, recommendations on the maintenance of an appropriate BMI with an emphasis on physical activity could be an important preventive strategy against the development of cervical cancer.

Project description:BackgroundPhysical activity is effective in preventing chronic diseases. However, the impact of different durations of exercise on human health is unknown, especially among people with diabetes or prediabetes.ObjectiveTo explore the relationship between high MET hours per week and the change in glomerular filtration rate (eGFR) in the total population and different subgroups.MethodsA total of 43767 individuals from eight provinces, in China, were recruited. Logistic analysis was used to investigate the association. Participants were divided into 3 groups based on MET hours per week. The primary outcome was an eGFR ≤ 90 mL/min/1.73 m2.ResultsThe average eGFR was 100.10 (92.43-106.43) mL/min/1.732. Logistic regression analysis revealed that more than 7.5 MET hours per week (equivalent to more than 150 minutes of moderate-intensity of exercise) was associated with the higher risk of the decreased eGFR even after adjusting for confounding factors (7.5 to <21: OR = 1.18, 95% CI [1.09, 1.29]; ≥21: OR = 1.12, 95% CI [1.05, 1.19], p for trend: 0.0047). After adjusting for confounding factors, in stratified analyses, there still existed a significant relationship among participants aged from 55 to less than 65 years, but not among participants younger than 55 or older than 65 years. Similarly, there existed a positive association between high MET hours per week and the decreased eGFR in participants without diabetes and prediabetes, but not in participants with diabetes or prediabetes, and the interactions of age and diabetic states were found. However, there was no significant difference in women or men.ConclusionsMore than 7.5 MET hours per week (equivalent to more than 150 minutes per week or 60 minutes per day of moderate-intensity exercise) was associated with decreased eGFR among participants aged from 55 to less than 65 years and participants without diabetes and prediabetes, but not among participants aged younger than 55 years and older than 65 years and participants with diabetes or prediabetes. The importance of planning individualized physical activities is highlighted.
